Security: mask settings secrets, remove hardcoded employee-DB creds

Browse Source 
- GET /settings now masks password/token values (were returned in plaintext
  to anonymous callers); sending the mask back on update is a no-op so the
  real secret is never clobbered.
- Move the employee-directory DB credentials out of source into env-backed
  config (shopdb.utils.employee_db); employees + notification recognition use
  the shared helper. Employee lookups stop leaking exception strings.
- Fix low-supplies report using loc.location instead of loc.locationname.

Employee/notification read endpoints stay unauthenticated by design (public
shopfloor kiosk displays consume them).
